Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Next time, please show us the question! Luckily I know that the question is asking "which of these is a function" but not a lot of people can assume that. The answer is B because a function can't have repeating x values or more than 1 x value that's the same. None of the x values in B repeat so it's a function! Also, remember that y values CAN repeat, so if the y values repeat, it doesn't mean it isn't a function.

Answer:

A.11

Step-by-step explanation:

i think 11 hours is the minimum number of hours that a car share needs to be used per year because it might also make Company B a more stabilized deal.

Answer:

A, 11

Step-by-step explanation:

Explanation: if you ignore the annual and just multiply both hourly by 10 and add the annually after they are both equivalent to 190 and since B costs less from 11 hours and beyond B will cost less.

Answer:

(f+d)/c  

Step-by-step explanation:

First get rid of -d on the left side by adding d to both sides

cx - d = f  -->   cx = f + d

Then remove c from the left side by dividing both sides by c.

cx = f + d  -->  x = (f + d)/c

Answer:

16

Step-by-step explanation:

5x + 2y - 7z    

(x = 2, y = 10, z = 2)

First things first you would want to take the letters that the numbers are equal to and replace them with the numbers.

5(2) + 2(10) - 7(2)

Then you multiply the number that's beside the parentheses, 5(2) is the same as 5 x 2.

5(2) = 10

2(10) = 20

7(2) = 14

so now you have

10 + 20 - 14

10 + 20 = 30

30 - 14 = 16

and 16 is your final answer!

Answer:

-1, 0, -1

f(x)=-1(x+0)^2-1

Step-by-step explanation:

vertex translated from (0,0) to (0,-1), so the function translated down by -1

f(x)=a(x-0)^2 -1

substitute (1,-2) to solve a,

a(1-0)^2 -1 = a-1 = -2

a=-1

thus, f(x)=-1 (x+0)^2 -1

Answer:

D because if you remove the song there will be no more numberrs which is the opposite.

Situations A, C and D are the correct answers.

From the options, we need to check the situations opposite to 80.

An integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero.

Now,

Situation A: An aeroplane descends 80 m, this can be represented in integer form as -80.

Situation B: An elevator ascends 80 m, this can be represented in integer form as 80.

Situation C: The cost of a train ticket drops by $80, which can be represented in integer form as -80.

Situation D: You remove 80 songs from an iPhone, which can be represented in integer form as -80.

Situation E: Suzy's grandmother is 80 years old, which can be represented in integer form as 80.

Therefore, situations A, C and D are the correct answers.

Answer: C

Step-by-step explanation: (1/5 in decimal form is 0.2) (25% in decimal form is 0.25) (then u got 1.3 and) (2/7 in decimal form is (0.28 so A= least D= greatest) A: least, B: middle C: to, D: greatest

so A: 1/5, B: 25% C: 2/7 D: 1.3

so your answer to this question is D

in order to find the biggest decimal you'll have to see which number is bigger in front of the decimal and if there is no number infront look right behind it, D is the greatest because 1.3 is another way of saying 1 whole and 1/3 but besides the point your answer is C

Answer:

2.5 miles

Step-by-step explanation:

We know that: time = distance/speed

Now, if the distance of the school from Jonathan's home is y.

At speed of 15 mph, Jonathans time is; time = y/15 hours

At 25 mph, his mother's time was;

time = y/25 hours

We are told that Jonathan was 1 mile from home when he saw his mother.

Thus means that difference in time is;

Time difference = 1/15 hours

Thus;

y/15 hours - y/25 hours = 1/15 hours

Multiply through by 75 to get;

5y - 3y = 5

2y = 5

y = 5/2

y = 2.5 miles

Answer:

We can infer a cause-and-effect relationship because multiple variables were included.

Step-by-step explanation:

The multiple attributes for the divorced ones are

1) less physically active

2) an unhealthy weight,

3) smokers.

The attribute showing the % of the married is

1) death

So when we compare the two groups married and divorced we see different variables are involved in evaluating the percentage.

This shows a cause and effect involving multiple variables.

In cause and effect one variable is dependent and the other is independent.

The cause is the independent variable and effect is the dependent variable.

CAUSE                          EFFECT

Married                         Death

Divorced                     1) less physically active

                                  2) an unhealthy weight,

                                     3) smokers.

Answer:

We cannot infer a cause-and-effect relationship because treatments were not assigned randomly.

Answer:

100*2/5, 6*3-8, 2/3+4*2, 5+3-8*10 goes to multiplication first. 100/2*5, 14-4/8, 15+8/4-6 goes to division first. (4+3)/2, 89+43-10 goes to addition first. 4-5+7 goes to subtraction first.

Step-by-step explanation:

Follow the order of the operations (Parenthesis, Exponents, Multiplication, Division, Addition and Subtraction.) Addition and subraction, multiplication and division gets determined by reading from left to right. Whichever comes first will be first calculated.

15+8/4= 8/4 is first. Division.

14-4/8= 4/8 is first. Division.

2/3+4*2= 4*2 is first. Multiplication.

100*2/5= Multiplication is first.

100/2*5=100/2. Division.

6*3-8=6*3. Multiplication.

(4+3)/2=(4+3). Addition.

Answer:

Step-by-step explanation:

5 times Z= 5x 2= 10

Answer:

−5x+13y=84

Step-by-step explanation:

I hope this is good :)

Answer:

We know that:

If T = area of the triangle

and R = area of the rectangle:

I T - RI < 4.

Now, we know that:

T = 8*6/2 = 8*3 = 24

R = 4*(x - 4) = 4*x - 16

Then replacing those values, we can write:

I24 - (4*x - 16)I < 4

I40 - 4*xI < 4

Now let's solve it:

First we aim for the first value that is not a solutions, this is when:

I40 - 4*xI = 4

we can write this as:

40 - 4*x = +-4

The first extreme is:

40 - 4*x = +4

x = (40 - 4)/4 = 9

The other extreme is:

40 - 4*x = -4

x = (40 + 4)/4 = 11.

Then the set of solutions is: S = (9, 11)

Answer:

900 people

Step-by-step explanation:

.36x=324

×=324÷.36

x=900

900 people were in the survey.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

324 indicated that they regularly work more than 45 hours a week.

and  36% of those surveyed.

let the total people surveyed be x

36% of x= 324

36 x/100 = 324

36 x = 32400

x= 32400 / 36

x= 900

Hence, total 900 people are surveyed.
